I'm a new owner of a 2005 6.0 Excursion, while I am far from being well versed on the 6.0 PowerStroke, my brother and best friend have been 7.3 guys for a while. Bro is soon to be upgrading and will most likely get a 6.0 of some sort.
My brother has filled me in on some of the 6.0 research he's been doing, EGR cooler problems, head bolt issues, and $800 FICM's.
My truck has 103,000mi on it, the EGR cooler was just replaced at a Ford dealer a day before I bought it (1 wk ago). and I wasted no time on spending some dough. I installed a SCT Livewire programmer, street tune(85hp I think), SCT's EGT sensor kit, shut off the EGR, and a AirRaid air filter. I have a down/cat delete pipe on order. Thats about all I was planing on for a while.
Well.. the check engine light came on today. Checked codes and got a PO611 and 5 other injector circuit low voltage codes. Looks like a FICM issue. I'm going to check the voltage as soon as I'm done posting.
My question is, did the tune push the FICM over the hill? Was it going to go anyway? I spent a couple minutes before signing up to the site researching the FICM, whats the best route? CircuitBoardMedics.com a way to go?
Any help would be appreciated
